With the purpose to compare the physical features of the electromagnetic field, we describe the synthesis of optical singularities propagating in the free space and on a metal surface. In both cases the electromagnetic field has a slit-shaped curve a

In this paper we extend the concept of perfect optical vortex to the vector case and investigate its focusing properties in the high numerical aperture regime. We show that simultaneous phase encoding of orthogonal components can be realized by means

We analyze the diffraction field generated by coherent illumination of a three-dimensional transmittance characterized by a slit-shape curve. Generic features are obtained using the Frenet-Serret equations, which allow a decomposition of the optical

Optical diffraction fields have in general a spatial complex structure and some times can generate focusing regions, in this work we describe the focusing region associated with highly symmetric transmittances, analyzing its associated phase function

We realize the design and synthesis of partially coherent secondary sources illuminating an ensemble of mobile transmittances in a tandem array. The motion states of the transmittances are random variables which are synchronized by means of the condi

The scattering field generated by the coherent illumination on a three-dimensional slit-curve is described through the trihedral reference system. The projected curves on the orthogonal planes carries on the information of the curvature and torsion g

We describe the synthesis of rough surfaces by means of a holographic technique. During the reconstruction process we obtain a speckle band gap, so that we can implement an amplitude-correlation interferometer. Bifurcation effects are identified.

In recent years, particle transport at microscopic level has become an important research topic which has led to the understanding of directed particle transport subjected to thermal fluctuations. Brownian motors (also called ratchet mechanism) are o

We describe the interaction between focusing regions and analyze the resulting physical features. The study is supported by the fact that focusing regions exhibit particle-like behavior and the interaction among these presents features similar to ine
